In 1945 they produced two prototypes with 75 cc 4-speed engines from which are derived the GT 98 which went into production in 1949, followed in 1951 by a 150 and in 1953 the Star 150, all with four-speed gearboxes.

Much later, they also assembled off-road machines using outsourced componentry.

The production of Sessa motorcycles spans the years 1948 to 1954 in the Morazzone factory which employed thirty people, while the frames are made in Azzate in a smaller factory employing 12.

All this thanks to the brothers Umberto and Alfredo Gianluigi, and their father Eugenio.

Eugenio Sessa in 1922 had created a motorcycle with sidecar equipped with a V-twin 1300 cc and then a single-cylinder, junction perhaps Della Ferrera, with rocker valves shoe, the discharge valve and single control for gearbox, clutch and gas.

The dynasty of Sessa part by his grandfather Joseph in Jerago, in the province of Varese, had a factory specializing in parts for carriages, particularly appreciated the production and requested the axles for coaches whose suffered pins a special process that made them safe and antiseizure ( a kind of cementing material) so as to enable the Sessa to become a supplier of the Royal British house.

After the production of parts for carriages were made spare parts for the automotive industry. The bike Sessa has become a widespread thanks to dealers De Palma Raffaini Milan and Parma.

A Morazzone worked a dozen people. The closure of the factory in 1954 Gianluigi goes in the motorcycle industry (Rumi, Bianchi and then Innocenti) and Umberto designs forks and shock absorbers.

The design of Sessa was also attended by Eng. Aldo Alice Gallarate, who came from Rumi.
